title: [The clinical significance of real-time fluorescence PCR quantification of hepatocyte growth factor mRNA expression in acute leukemia].
abstract: OBJECTIVE
  To detect quantitatively hepatocyte growth factor (HGF) mRNA expressions of bone marrow mononuclear cells (MNCs) in acute leukemia (AL) and investigate its clinical significance.
  
  
  METHODS
  Total mRNA of quantitated bone marrow MNCs isolated from 67 de novo AL cases was extracted and then cDNA was synthesized. Expression of HGF mRNA was quantified absolutely using real-time fluorescence quantification PCR (FQ-PCR).
  
  
  RESULTS
  Expressions of HGF mRNA in a group of AL were higher significantly than these in a control group (6.936 +/- 1.613, 0.407 +/- 0.170, P < 0.001), but there was similarity between a group of acute myeloid leukemia (AML) and group of acute lymphoblastic leukemia (ALL) (7.127 +/- 1.911, 6.635 +/- 0.934, P > 0.05). In AL subtypes, the expression of M5 (9.998 +/- 1.454) was higher than that of M2, M3, M4, L1, L2 and L3 (P < 0.001), but there were no differences among the latters (P > 0.05). Meanwhile, there was no statistical significance on the expressions of HGF mRNA between different age and sex (P > 0.05). In addition, expressions of HGF mRNA in the remission group were lower than these in the non-remission group (6.393 +/- 1.165, 8.041 +/- 1.848, P < 0.005).
  
  
  CONCLUSIONS
  There are statistical significances of the expressions of bone marrow MNCs HGF mRNA among the AL group and control group. As to AL subtypes, there are no statistically significant differences between AML and ALL as well as between different age and sex. Besides, lower HGF mRNA level is correlated with better curative effect. It is suggested that HGF mRNA is a suitable index for AL diagnosis and treatment.
